Protection of Per-
sons and Equip-
ment
The design and function of the inverter offer a maximum level of safety, both during instal-
lation as well as operation.
The inverter provides operator and equipment protection through:
a) galvanic isolation
b) monitoring the grid
Galvanic isolation The inverter is equipped with a high frequency transformer that ensures galvanic isolation
between the DC side and the grid, thus ensuring the highest possible safety.
Monitoring the
Grid
Whenever conditions in the electric grid are inconsistent with standard conditions (for ex-
ample, grid switch-off, interruption), the inverter will immediately stop operating and inter-
rupt the supply of power into the grid.
Grid monitoring is carried out using:
- Voltage monitoring
- Frequency monitoring
- Monitoring islanding conditions
Warning notices
affixed to the de-
vice
The inverter contains warning notices and safety symbols. These warning notices and
safety symbols must NOT be removed or painted over. The notices and symbols warn
against operating the equipment incorrectly, as this may result in serious injury and dam-
age.
WARNING! If the equipment is used or tasks are carried out incorrectly, serious
injury or damage may result. Only qualified personnel are authorized to install
your inverter and only within the scope of the respective technical regulations. It
is essential that you read the "Safety regulations" chapter before commissioning
the equipment or carrying out maintenance work.
